   1 Imagination Technologies hardware hash accelerator
   2
   3 The hash accelerator provides hardware hashing acceleration for
   4 SHA1, SHA224, SHA256 and MD5 hashes
   5
   6 Required properties:
   7
   8 - compatible : "img,hash-accelerator"
   9 - reg : Offset and length of the register set for the module, and the DMA port
  10 - interrupts : The designated IRQ line for the hashing module.
  11 - dmas : DMA specifier as per Documentation/devicetree/bindings/dma/dma.txt
  12 - dma-names : Should be "tx"
  13 - clocks : Clock specifiers
  14 - clock-names : "sys" Used to clock the hash block registers
  15                 "hash" Used to clock data through the accelerator
  16
  17 Example:
  18
  19         hash: hash@18149600 {
  20         compatible = "img,hash-accelerator";
  21                 reg = <0x18149600 0x100>, <0x18101100 0x4>;
  22                 interrupts = <GIC_SHARED 59 IRQ_TYPE_LEVEL_HIGH>;
  23                 dmas = <&dma 8 0xffffffff 0>;
  24                 dma-names = "tx";
  25                 clocks = <&cr_periph SYS_CLK_HASH>, <&clk_periph PERIPH_CLK_ROM>;
  26                 clock-names = "sys", "hash";
  27         };
